What does a speed rating of H mean?

SPEED RATING H

If you recall from earlier, the “H” speed rating doesn't appear after “G” but between “U” and “V.” It represents a maximum speed of 130 mph (210 kph) and is commonly found on sports sedans and coupes.

Which speed rating is better H or T?

The “T” or “H” on tires pertain to their speed ratings. A T-rated tire can withstand top speeds of up to 118 mph (190 km/h), while an H-rated tire can support up to 130 mph (210 km/h). It is important to note these markings and stay within those speed limits.

What does H or V speed rating mean?

An “H” rated tire is designed to operate at a maximum speed of 130 mph. A “V” rated tire on the other hand is designed to operate at a maximum speed of 149 mph, almost twenty miles an hour more than the “H” rated tire.

What does performance rating H mean?

An H speed rating indicates the tire is approved for speeds up to 130 mph (210 km/h) under optimal conditions. An H speed rating is at the low end, or start of the performance tire speed ratings.

What does H stand for on Tyres?

Each letter denotes the maximum speed a tyre can sustain under its recommended load capacity. In our example, “H” is equivalent to a maximum speed of 130 mph (209 kph).

What Is A Tire Speed Rating?

What does H mean on tires?

“H” represents the speed rating, which is how fast the tires can go based on their load capacity. This rating ranges from A – Z. “H” indicates a speed rating of up to 130 mph.

What is load range H?

From a G to an H

Truck tires typically come in two load ratings: G and H. Load range G is a 14-ply configuration, while load range H tires have 16 plies. The heavier-rated tire will usually add between 700 pounds and 1,000 pounds more load-bearing capacity per tire (see "How Much is Too Much," next page).

Do higher speed rated tires wear faster?

They're also about ride comfort, wear and cornering ability. Typically, the higher the speed rating, the better the grip and stopping power, but the lower the tread life.

Can you mix T and H rated tires?

Just remember, never mix and match tires with different speed ratings on your vehicle. This will cause major problems with the handling of your vehicle. If tires of different speed ratings are mounted on a vehicle, the lower speed-rated tires should be placed on the front axle, regardless of which axle is driven.

Can I replace H rated tires with V?

A V-rated car requires a tire designed to operate to a maximum of 149 mph and can thus not be fitted with an H-rated tire.

What is the H rating on a motorcycle tire?

The H speed index means the tire is rated at a maximum of 130 mph. Load and speed index maximums are very important for you to consider when purchasing tires. The higher the load number, the more weight the tire can handle.

Can I use W rated tires instead of V?

V means that vehicles can safely use the tire with a top speed higher than 149mph. The rating W shows that the tire is safe to use for a vehicle with a top speed of 168mph.

Do speed ratings on tires matter?

The speed rating tells you the speed the tire can safely maintain over time. A higher speed rating usually means you will have better control and handling at higher speeds - and that the tire can take the extra heat. As a general rule, tires with higher speed ratings also handle better at slower speeds.

What is the difference between AT and HT tires?

AT tyres have a deeper and more aggressive tread than HT tyres. This provides greater grip in off-road conditions. Generally speaking, the stronger, thicker sidewalls of an AT tyre make them less likely to suffer damage caused by common hazards encountered off-road, such as rocks, ruts and tree roots.

What does 98H mean on tires?

The load index and speed ratings are grouped together, denoted, for example, as 98H. The load index is a number that generally ranges from 75 to 105; the higher the number, the more weight the tire can support. The speed rating is expressed with letters, and there are several.

Does tire speed rating affect gas mileage?

The short answer: yes. Tires can make a big difference in the number of miles a driver gets to a tank of gas. And it's not all about tire maintenance; even the kind of tire on the car can affect the fuel economy. It all comes down to rolling resistance, how the tire overcomes inertia.

Which is better 6 ply or 8 ply tires?

Actually the 6 ply will last longer than the 8 ply. The reason is the extra size of the body plies in a trailer tire will actually produce more heat while rolling than a 6 ply rated tire. I definately recommend radila and not bias ply construction. Radial tires wear much better.

What load rating do I need?

To roughly determine the load range capacity for each individual tire, take the vehicle's gross weight and divide by four. If the vehicle gross weight is 4,500 pounds, each tire should be able to safely support at least 1,125 pounds.

What are Z rated tires?

While a Z-speed rating still often appears in the tire size of some tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph; the W in the service description indicates the tire's specific 168 mph maximum speed.

How long are tires good for?

On average, people drive between 12,000 to 15,000 miles a year, which means the average good quality all-season tire will last somewhere between three and five years, depending on maintenance, driving style and conditions, etc.

What does 71 H mean on motorcycle tire?

It seems to fit with a standard alpha system, except for the last two figures: 71 H . Here, 71 indicates the load index (see Load Index Chart ). The “H” is a speed rating.

What does 74 H mean on a motorcycle tire?

Going hand-in-hand with the alphanumeric way of measuring, the service description is a combination of a tire's load index and speed rating. For example, a tire with the sizing MT90B16 74H has a load index of 74 and a speed rating of H (130 mph).

What does 55w mean on a motorcycle tire?

Our second number, 55 here, is the aspect ratio of the tire. This means that the tire's measurement from inside the bead (which sits inside the wheel rim holding the tire within it) to the top of the tire is 55% of the tire's width. In this example, 55% of 180 millimeters is 99 millimeters or 3.9 inches.
